Cooling fan unit and display apparatus having the same

Abstract

A display apparatus having a casing in which an opening part is formed, includes: a liquid crystal display panel that is supported by the casing so that an image can be displayed through an opening part; a backlight unit that is provided behind the liquid crystal display panel and has a light source that emits light; a shield cover that is provided behind the backlight unit and is supported by at least one of the backlight unit and the casing; and a cooling fan unit that is combined to the shield cover and supplies cooling air to the backlight unit.

1. A display apparatus having a casing in which an opening part is formed, comprising:
 a liquid crystal display panel that is supported by the casing so that an image can be displayed through an opening part; 
 a backlight unit that is provided behind the liquid crystal display panel and has a light source that emits light; 
 a shield cover that is provided behind the backlight unit and is supported by at least one of the backlight unit and the casing; 
 a cooling fan unit that is combined with the shield cover and supplies cooling air to the backlight unit, and 
 wherein the cooling fan unit comprises a cooling fan and a fan cover that has one side provided with a first combining part combined with the cooling fan and the other side provided with a second combining part combined with the shield cover. 
 
   
   
     2. The display apparatus according to  claim 1 , wherein the light source comprises light emitting diodes (LEDs). 
   
   
     3. The display apparatus according to  claim 1 , wherein the shield cover is provided with a fan support that supports the cooling fan unit, the fan support being distanced from the casing and being formed at a position adjacent to the backlight unit. 
   
   
     4. The display apparatus according to  claim 3 , wherein the fan support is formed at a central lower portion of the shield cover. 
   
   
     5. The display apparatus according to  claim 1 , wherein the casing and the shield cover are provided with a plurality of air slits through which air generated by the cooling fan unit comes in and out. 
   
   
     6. The display apparatus according to  claim 1 , wherein the first combining part comprises:
 a first support that supports the cooling fan and the fan cover; and 
 a first joining member that joins the cooling fan with the fan cover. 
 
   
   
     7. The display apparatus according to  claim 6 , wherein the first combining part further comprises a first vibration absorption member that is disposed between a plurality of the first supports and absorbs vibration generated from the cooling fan. 
   
   
     8. The display apparatus according to  claim 1 , wherein the second combining part comprises:
 a second support that supports the fan cover and the shield cover mutually; and 
 a second joining member that joins the fan cover with the shield cover. 
 
   
   
     9. The display apparatus according to  claim 8 , wherein the second combining part further comprises a second vibration absorption member that is disposed between a plurality of second supports and absorbs vibration generated from the cooling fan. 
   
   
     10. The display apparatus according to  claim 8 , wherein each of the first support and the second support is provided plural in number. 
   
   
     11. The display apparatus according to  claim 8 , wherein each of the first joining member and the second joining member comprises a screw.
